SPECIFICATION forming part of Letters Patent No. 588,543, dated August 17, 1897.

I Application filed January 16, 1897. Serial No. 619,446. (No model.)

To all whom it may concern:

Be it known that l', SILAs S. BRADSHAW, a

citizen of the United States, residing in Brooklyn, Kings county, and State of New York, have invented a new anduseful Improvement in Railway-OarWindows, of which the fol? lowing is a specication.

My invention relates especially to the construction and arrangement of car-window sashes, and has for its object the provision of means and mechanism which will prevent rattling or jarring of the sash and at the same time exclude dust, dirt, and drafts and permitting the sash to be raised' and lowered with perfect ease, expansion and contraction of the wood of the sash and frame 4having no effect whatever upon my invention.

To attain the desired end, my invention consists, essentially, in certain novel and useful combinations or arran gem ents of parts and occur, indicate corresponding parts in all the 5, said rods 4 being normally forced outward by means of springs 6. The rod et is movably held in-place in the groove 3 in like manner. 7 is the Window-sill; 8, the parting or blind stop; 9, the blind; 10, the inner stop, and 11 the outer stop. w Y

When constructed and arranged in accordance with the foregoing description, my improved car-window sash will be found very eflicacious, while extremely simple in construction and easy to apply. The.springactu ated rods at the sid es will prevent all rattling, excluding dust, dirt, and drafts, and as it is not necessary to iit the sash tightly in the lframe it may be raised and lowered with slight effort, and at the same time the expansion and contraction of the sash and frame caused by changes inV the atmosphere will have no effect whatever upon my device. The rod in the lower rail of the sash will bear snugly against the sill when the'sash is closed down, acting in substantiallyv the same manner as the rods in the stiles.

Having now fully described my invention,- what I claim as new therein, and desire Ato secure by Letters Patent, is

l. The combination with a window-sash having grooves in the faces of the stiles and in the lower edge of the bottom rail, of springactuated rods or bars movably locatedin said grooves, substantially as shown and described.

2. In a car-Window, a sash having grooves in the faces of the Stiles, in combination with spring-actuated rods or bars movably mount-A ed in said grooves, substantially as shown and described.

SILAS S. BRADSHAW.
